VESOUL nouvelle Wastewater Treatment Plant, Vaivre-et-Montoille, France

VESOUL nouvelle is a municipal wastewater treatment plant located in Vaivre-et-Montoille, serving the urban area of Vesoul in the Haute-Saône department of Bourgogne-Franche-Comté, France. The plant handles wastewater from a population equivalent of approximately 67,586, placing it in the medium-to-large agglomeration category under French regulations. As a French wastewater treatment facility, VESOUL nouvelle operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's discharge must comply with national standards set by the French Ministry of Ecology, with permits issued by the local water agency (Agence de l'Eau). The treated effluent is discharged into the local watershed, which ultimately drains into the Saône River, a major tributary of the Rhône. The Rhône flows into the Mediterranean Sea, making the plant's performance important for downstream water quality in the Saône and Rhône basins.

The plant discharges into the Saône River basin, which flows through eastern France before joining the Rhône near Lyon. The Rhône then empties into the Mediterranean Sea. The Saône supports diverse aquatic life and is used for recreation and agriculture. Proper treatment is essential to prevent nutrient pollution and protect downstream ecosystems, including the Camargue delta region.
